petplanet Posted June 10, 2006 Report Share Posted June 10, 2006 Did some tests today Tank One: MG 1710 JBL Test Kit CA360 JBL Test Kit pH 8.6 Salifert pH 8.2 Seachem KH 8.45 Salifert Alk 3.03 Salifert Alk 2.5 Seachem Salinity 1.030 Tank Two MG 1900 JBL CA 360 JBL pH 8.23 Electronic pH 8.6 Salifert pH 8.3 Seachem KH 14.4 Salifert Alk 5.14 Salifert Alk 4.5 Seachem Salinity 1.025 Did reference tests for the Seachem pH and Alk and they are correct. Did a pH test with the Salifert on RO water and it read 7.4. Did all the MG tests twice and still got the same readings. I have been adding a fair bit of magnesium chloride but it should not have gone this high. Calcium levels seem to be dropping as the MG level increases. On the bright side my Heteactis magnifica anemone has doubled in size in the last month! Quote Link to comment Share on other sites More sharing options...

petplanet Posted June 10, 2006 Author Report Share Posted June 10, 2006 Nope. Tank one used to have VERY high phosphate and nitrate and had zero algae. 3 very efficient tangs. I have to clean the glass every three days but the rocks are very clean. The other tank is not quite as good but the Tangs are on a diet so should lift thier game. I added a lawn mower blenny who had run out of algae in another tank (to efficient for its own good) and it is already having an impact.

cookie extreme Posted June 10, 2006 Report Share Posted June 10, 2006 did you subtract the calcium total from the total (magnesium)? Quote Link to comment Share on other sites More sharing options...

cookie extreme Posted June 11, 2006 Report Share Posted June 11, 2006 can you please explain thats how the JBL test works. it messures total magnesium with calcium. you then messure only calcium with a separate test and deduct this figure from the first. so if you don't do that your mag will look really high and taht what i thought happened.
